I usually dump this hand in every position. Even at the stakes I play (NL25), there's still the chance that some a-hole limped in EP with AK/AQ. I've been burned time and time again.

With that said....I am a camper. I play tighter than tight, so I may not be a good one to ask.

I think it would be a good play to limp MP and dump if raised......or to raise in LP with no raisers and very few callers in front of you too.
